Part sodium carbonate, add clear water in carrying out 5 ~ 10h of immersion under Ultrasonic Conditions；The Concave-convex clay rod after immersion is taken to be stirred
And extrusion molding, Concave-convex clay rod thin slice is obtained, then by thin slice and 3 ~ 5 parts of polyacrylamide, 1 ~ 3 part of epoxy resin and fibre
1 ~ 3 part of dimension element is uniformly mixed, and is ground to particle diameter for 100 ~ 150 mesh；
（2）The preparation of attapulgite clay foaming agent：10 ~ 20 parts of raw material Concave-convex clay rod, ten of following weight portion are weighed respectively
1 ~ 3 part of sodium dialkyl sulfate, 1 ~ 3 part of Sodium Polyacrylate, 1 ~ 3 part of SODIUM PERCARBONATE are mixed and stirred for uniformly, being ground by grinder
It is 100 ~ 150 mesh to particle diameter；
（3）The preparation of acoustic brick：
First, glass fibre, diatomite, calcium carbonate, silica flour are weighed respectively according to proportioning, be uniformly mixed, and by its powder
100 ~ 200 mesh are broken to, compound one is obtained after drying；
Secondly, high viscous Concave-convex clay rod, paste attapulgite clay are well mixed, are then added successively under agitation again
Enter compound one, graphite and foaming agent, be well mixed, obtain compound two；
Again, compound two is carried out into mould molding, is dried after die sinking, calcines and be warming up to 800 ~ 1000 DEG C, then it is permanent
Temperature 3 ~ 5h of roasting, cooling, cutting obtains final product the acoustic brick.
7. the preparation method of concave convex rod acoustic brick according to claim 6, it is characterised in that：The step（1）Middle stirring
And the method for extrusion molding is that Concave-convex clay rod is added in mixer to be stirred, will by extruder after stirring
Concave-convex clay rod extrusion molding is thin slice.
8. the preparation method of concave convex rod acoustic brick according to claim 6, it is characterised in that：The step（3）Middle mixing
It is that compound two is added in forging press to be forged under the conditions of 90 ~ 100MPa that material two carries out formed in mould method
Type.
